It's a great game that sadly appears to be have been discontinued.
I did my part but it wasn't enough....
So, what's strats do you use?
I basically use as many Allies with Guard and/or Block as I can, along with as many cheap Attachments that either boost attack or grant Block. I then try to get all of my heroes Block and boosted Attack as quickly as possible. I then use Allies to tank enemy attacks while my Heroes clear objectives or defeat key enemies. I rarely use Event cards because Sauron always seem to cancel them when I really need them to work.
Because of my approach, I mostly rely on Leadership heroes (Dis and Aragorn are both excellent and Dain is great if you build a deck around his passive). For my Tactics hero, I use Boromir a lot since he can both grant Block to a character *and* boost their attack.
I don't really like any of the Lore Heroes. None of them seems to have a good ability. But maybe I just don't know how to use them properly.
It also seems like the Hobbit heroes are all crap. Well, except for Frodo. His innate Stealth ability allows him to avoid damage and then he can pop out of Stealth at the end of a round to clear an objective before Sauron can react. He's extremely useful.
Been a while since I played.
I eventually got skilled at keeping allies alive, to the point that the "standard" number of allies in my deck only created lots unused card in my end.
So I began to add events and low-cost attachments in additions to the big "bombs", running decks light in creatures.
My inclination is towards board presence anyway.
Trying to anticipate who's gonna be hit by the next attack, I try to adjust my tactics in such a way that the damage gets spread around while preserving the number of creatures on the table.
Then I proceed to slowly turn the tide around.
Healing powers are great for this. There's a elf ally (IIRC) that heals 1 damage to a character of your choice (even non hero) every time you kill a foe. That's actually great as it adds up.
Sometimes I even had two on the fields, you could have a pretty stable row of healthy characters with such a setup.
(I mean of course you'd cast one when you already have a bit of presence)
A new foe arrives and it's toast.
In general, it goes without saying, but especially at the start of the battle when you have only 3 heroes, you should beeline for the build-up of the board and/or using abilities, spells or weapons that give you more actions.
That's a major thing in this game. That brooch item, for instance, or the Courage spell.
Then a lot depends on the the specific constraints (and unlockable bonuses) of the quests. Sometimes a bonus is so good that it's preferable to beeline for that, even skipping the lower-tier ones, spending early actions to unlock it asap (for instance when it grants a strong ally, or a bonus to everyone's attack rating, stuff like that).
But I'm sure I'm forgetting a lot of things.
I was pretty disappointed with this game not getting more content, I kinda stopped playing for that but I probably shouldn't have.
It's really fun and well designed.
